Predictably, Skiles didn't reveal any more. But with the Heat's scorching offensive starts in Games 1 and 2, defense is likely the priority. Skiles may be willing to risk early foul trouble on Tyson Chandler, or perhaps insert Luol Deng. He could put in Chris Duhon for Ben Gordon, whose defense Skiles said has been lacking.

Certainly, a replacement for Malik Allen could be in store. The veteran sat out practice Wednesday after back spasms kept him out of the building entirely Tuesday. Skiles said Allen likely will be ready for Game 3--but if "ready" doesn't mean 100 percent, Chandler or Deng takes his starting slot.

Whatever the combo, it must not be soft defensively in a must-win game.

"At this time of year, even playing in an empty gym, you ought to be ready to roll," Skiles said. "I expect them to come out strong. I just hope we come out better. Both games we just have been back on our heels right at the beginning."

Layups

Chandler's wife, Kimberly, still had not given birth to the couple's first child as of the end of practice Wednesday. "She's a stubborn baby," Chandler said. "She likes it in there." The 7-footer's plan is to play even if the birth is imminent. . . . Skiles said Udonis Haslem's return after a one-game suspension should help Miami. "He's another skilled player who can make shots," the Bulls coach said. . . . Tickets are still available for Games 3 and 4.
